tdf#131060 tdf#117088 chart view: fix missing or truncated axis labels
if we have enough space under the horizontal X axis.
Note: allow truncation of vertical X axis labels only if they
are text labels and the position is NEAR_AXIS or OUTSIDE_START.
Regressions from commit 35d062f7879d5414334643cb90bff411726b2168
(tdf#116163: Limit label height in chart if needed)
and commit 26caf1bc59c81704f11225e3e431e412deb8c475
(tdf#114179: Custom size and position of the chart wall)
